Sash-fastener



UNITED STATES PATENT OEEIeE.

HENRY S. KLEIN AND HENRY E. KLEIN, OF MILWAUKEE, \VISCONSIN.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 410,837, dated September 10, 1889.

Application filed March 1, 1889.

To all whom it may concern:

Be it known that We, HENRY S. KLEIN and I HENRY E. KLEIN, of Mih ankee, in the county of Milwaukee, and in the State of WVisconsin, have invented certain new and useful Improvements in Windows; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to Windows; and it consists in certain peculiarities of construction and combination of parts to be hereinafter described with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a front elevation of our 1nvention, partly in section; Fig. 2, a horizontal section on line 2 2 of Fig. 1; Fig. 3, a vertical transverse section on line 3 3 of Fig. 1, and Fig. 4 a detail View of a latch mechanism that forms part of our invention.

Referring by letter to the drawings, A B represent the side pieces of a window-frame.

Secured to the side piece B between the binding-strips O for the window-sash is a rack D, designed .for engagement with the flattened end I) of a rod E, the latter being arranged to slide in the bottom rail F and stile G of the sash and held against turning by means of a slotted plate II, slipped onto its flattened end and secured to said stile. The inner end 0 of the sliding rod E is reduced and screwthreaded in the socketed end cl of a rack-bar I, the latter being extended through an end wall of a casing J, that is mortised in the bottom rail F of the window-sash and covered by a face-plate K, secured to said rail.

A spring L is secured within the casing J to exert its force against a bend e in the rackbar I, and a toothed segment M is also arranged Within said casing to mesh with said rack-bar. The toothed segment M is fast to a stem f, that projects from a thumb-piece N,

and this stem has its bearings in the rear wall of the casing J and the face-plate K, the latter being provided with a finger-rest g in opposition to said'thumb-piece.

By pressing down on the thumb-piece N the toothed segment is operated to actuate the rack-bar 1, and thus the flattened end 19 of the latter is withdrawn from engagement with the rack D, in order to permit the raising of the Serial No. 301,702. (No model.)

window-sash. On the release of the thumbpiece N the spring L forces the rack-bar I back to its normal position, and thus the rack D and rod E are again engaged and the window-sash locked in the position to which it has been adjusted.

By the peculiar construction and arrangement of parts above described the mechanism that locks the window-sash in its adjusted position is concealed and protected from dirt.

Like in our patent, No. 392,924, issued No- Vember 13, 1888, the stiles of the sash have their outer edges cut to form a groove h, that gradually increases in depth from about the center toward its extremities, at which points it is deepened laterally to form recesses, as best illustrated in Fig. 1, and secured to the sash-stiles within the grooves h are semi-elliptic springs P, each of the latter having its ends provided with bearings for the journals of anti-friction rollers R or R, that travel on the side strips A B of the window-frame.

The lower roller R, journaled to the semielliptic spring P, adjacent to the rack D, is necessarily constructed in such a manner as to permit of its straddling said rack, as best illustrated in Fig. 2.

By the above construction it will be seen that we provide a very simple easily-operated window whose sash can be automatically locked at any height to which it may be adjusted, and our improvements can be readily applied to any window now in use without any material alteration or expense.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a window, the combination, with the frame and sash, of a rack secured to a side piece of said frame, a sliding rod arranged in said sash to engage the rack and havinga screw-threaded inner end, a rack-bar provided with a socket to engage said screwthreaded end of the sliding rod, and a pivotal toothed segment arranged to mesh with said rack-bar, substantially as set forth.

2. In a window, the combination, with the frame and sash, of a rack secured to a side piece of said frame, a sliding rod arranged in said sash, a casing mortised in the lower sash-rail and provided with a detachable faceplate having a finger-rest projecting thereand State of \Viseonsin, and at Ashland, in from, a rack-bar arranged Within the casing the county of Ashland, and in the State of and detachahly connected to the sliding rod, \Viseonsin, each in the presence of two wit- 15 a stem having its hearings in said casing and nesses.

5 faceplate and terminated in a thu1nb-pieee, HENRY S. KLEIN. a toothed segment arranged on the stem to HENRY E. KLEIN. engage the rack-bar, and a spring arranged \Vitnesses for Henry S. Klein: to exert its force against said rack-bar, snb- N. E. OLIPI-IANT, st-antially as set forth. \VILLIAH KLUG.

we have hereunto respectively set our hands, C, E. STREES, at Milwaukee, in the county of llIilwankee E. H. ELLIS.
